WED STAfeLTENT 0mm" THOMAS MARQUIS, OF NEWYORK, N. Y.

FLIER FOR 'ROVING, 65o.

Specification of Letters Patent No. 5,892, dated October 31, 1811,18'.

To all 'whom t may concern:

Be it known that I, THOMAS MARQUIS, of the city, county, and State of New York,

vhave invented an Improved Flier for Roving and Slubbing Cotton, and hereby declare the following is a full and eXact description ofthe same, reference being had to the annexed drawings, which make a part of this specification.

My improvement consists of a seat and guide fitted to the leg of the Hier of machines for roving and slubbing cotton, so as to conduct the sliver, and aord any required pressure upon the bobbin without the intervention of a spring or springs. The seatis a cylindrical piece of copper having an opening so as to Ht on to the leg of the Hier. This opening is not `in the center, consequently one section of the seat is thicker and heavier than the other. The guide is fast- 'ened to the seat opposite its heaviest section.

The result is that when the Hier revolves, the seat by having its outer section heavier than the inner, moves the guide inward. This preponderating part of the sea-t can be mo-re or less as pressure uponthe bobbin is required. Hence by this device no springs are needed. In some cases I substitute a fan for the preponderating seat of the Hier. In this device the seat and guide may be fitted on to the leg of the Hier, as before described, the seat being of no greater thickness than would be necessary to carry the guide and the fan, the latter being fitted on to the periphery of the former. The length or dimensions of the seat would be proportional to the length of the fan. The effect of the guide to press inward would thus be obtained by the fan meet-ing the atmosphere when the Hier is in motion. I also strengthen the legs of the Hier by a cross bar which is introduced so as to embrace both legs and the boss of the Hier, as low down as the boss will admit.

Figure l, view of a Hier with my improvement. A, A5, legs of the Hier in the form of hollow cylinders open at both ends. b, b 'a niche or slot through which the sliver is passed, a corresponding niche is on the opposite leg, not shown on the drawing. c, c, lower end of one of the legs reduced in diameter so as to admit the seat of the guide.

d, is a cast rim extending one half of the I y circumference of the lower end of the leg, so as to retain the seat of the guide, and to act as a stop to the guide marked f, f.

g', g, is the seat of the guide and f, f, th Y the leg of theiier. Z), b, the preponderat-V ing side.

Fig. 3, is a section through the Hier; a, a, a, a, the hollow cylinders of the legs. b, b, theboss; c, c, the cross bar embracing the two legs so as to give them strength to allow the machinery tol be driven at any speed. In Fig. 3, d, d, is the seat, e, e, the fan which is of thin metal let into it, f, f, the Hier.

What I claim as my invention and desire to secure by Letters Patent is The mode ofv moving and pressing the guide of the Hier (of a machine for roving and slubbing cotton) inward so as to conduct the sliver to the bobbing without the use of springs as herein described.

THOMAS MARQUIS.
